DETAILED DESCRIPTION

[0024] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0025] See also Figures 1 to 4 The utility model provides a technical solution: a heatable aluminum foil lunch box with a suction cup, comprising a lunch box body 1, which is made of aluminum foil by stamping. A handle 2 is arranged on the outside of the lunch box body 1, and the number of the handles 2 is at least two. The handle 2 is a hand-held component and is made of non-heat-conductive material, which is convenient for hand-held transfer of the lunch box body 1. A positioning tube 3 is detachably connected to the bottom of the handle 2, and a positioning suction cup 4 located below the handle 2 is connected to the bottom of the positioning tube 3. After the lunch box body 1 is placed on a plane, the positioning suction cup 4 will be adsorbed on the plane, thereby improving the stability of the placement of the lightweight lunch box body 1.

[0026] The top of the positioning tube 3 is axially elastically slidably connected with a pressing plug rod 5, which is a manually pressed component. The inner cavity of the positioning suction cup 4 is connected to the inner cavity of the positioning tube 3. When the pressing plug rod 5 is manually pushed downward, the air pressure in the positioning tube 3 increases. At this time, the positioning suction cup 4 is filled with gas, which facilitates the positioning suction cup 4 to be separated from the placement plane. Therefore, the foil lunch box with a suction cup has the advantages of stable placement and more convenient taking. Among them, the bottom of the pressing plug rod 5 is fixedly connected with a piston disk 51 sleeved in the positioning tube 3, and the positioning tube 3 is sleeved with a support spring 6 with the top and the piston disk 51 against each other. When the pressing plug rod 5 is pressed, the piston disk 51 slides downward, the support spring 6 is compressed, and the gas in the positioning tube 3 will enter the positioning suction cup 4, so that the positioning suction cup 4 can be quickly separated from the placement inside.

[0027] Specifically, the handle 2 is groove-shaped and fixedly connected to the lunch box body 1 at both ends. A necked tube 31 is welded to the bottom of the positioning tube 3. A positioning hole 21 that is plugged into the necked tube 31 is opened at the bottom of the handle 2. The positioning suction cup 4 is bonded to the bottom of the necked tube 31. The outer diameter of the necked tube 31 is smaller than the outer diameter of the positioning tube 3. The positioning tube 3 can be removed by pulling it upward as a whole. When the positioning tube 3 is removed, the positioning suction cup 4 will be removed together. After the positioning suction cup 4 is removed, it is convenient to put the lunch box body 1 into a microwave heating device for heating, which can effectively prevent the positioning suction cup 4 from being affected by microwave heating.

[0028] Furthermore, a rubber sleeve 211 is nested in the positioning hole 21 and is interference fit with the neck reduction tube 31. This arrangement makes the docking and separation of the neck reduction tube 31 and the rubber sleeve 211 more convenient. The inner diameter of the rubber sleeve 211 is larger than the outer diameter of the positioning suction cup 4, and the resistance of the positioning suction cup 4 entering and exiting the rubber sleeve 211 is greatly reduced.

[0029] In this embodiment, a clearance hole 22 that matches the clearance of the push-stopper rod 5 is opened at the top of the handle 2. The clearance of the push-stopper rod 5 passes through the clearance hole 22, which is convenient for manually holding the handle 2 and using the thumb to push the push-stopper rod 5 downward. It should be noted that when disassembling the positioning tube 3, the positioning tube 3 can be lifted up and then tilted downward to disengage the push-stopper rod 5 from the clearance hole 22, so that the entire positioning tube 3 is disassembled, and the positioning tube 3 can be reset by reverse operation.

[0030] In this embodiment, the free ends of the handle 2 are respectively welded with an upper reinforcement ring 23 and a lower reinforcement ring 24 which are sleeved outside the lunch box body 1. This arrangement can improve the strength of the connection between the handle 2 and the lunch box body 1.

[0031] Furthermore, the lunch box body 1 is a cone with the small end facing downward, and the outer peripheral wall of the lunch box body 1 is provided with an upper annular recess 11 and a lower annular recess 12 respectively adapted to the upper reinforcing ring 23 and the lower reinforcing ring 24, and the upper reinforcing ring 23 and the lower reinforcing ring 24 are respectively connected with the upper annular recess 11 and the lower annular recess 12 by clamping. When connecting, the upper reinforcing ring 23 and the lower reinforcing ring 24 can be divided into two halves, and then aligned with the upper annular recess 11 and the lower annular recess 12 and then welded end to end, thereby improving the deformation resistance of the lunch box body 1.

[0032] Working principle: When the lunch box body 1 needs to be placed on a placement plane, hold the handle 2 to place the lunch box body 1 on the placement plane, then press the handle 2, the positioning suction cup 4 is adsorbed and connected to the placement plane, and the stability of the placement of the lunch box body 1 is improved. When the lunch box body 1 needs to be separated from the placement surface, manually push the pressing plug rod 5 downward, the support spring 6 in the positioning tube 3 is compressed, the air pressure in the positioning suction cup 4 increases and separates from the placement surface, and the lunch box body 1 can be easily taken. When the lunch box body 1 needs to be heated using a heating device, manually pull the positioning tube 3 outward, the positioning tube 3 is separated from the handle 2, and the positioning suction cup 4 is removed, thereby preventing the positioning suction cup 4 from being damaged by heating.

[0033] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
